LITTLE ROCK (AP) — Little Rock's Bill and Hillary Clinton National Airport is unveiling its new baggage-screening system that's part of the airport's planned $67 million in improvements.

The airport says the new system unveiled Tuesday will allow Transportation Security Administration workers to screen more than double the amount of luggage per hour compared with the prior system.

Before, travelers needed to carry their checked bags from the ticket counter to the TSA screeners. The new system allows passengers to drop their checked bags directly with the ticket agents.

The new system is in use by Southwest Airlines, US Airways, Frontier Airlines and United Airlines. The airport says American Airlines will begin using the system by the end of the year when new ticket counters are completed in the airport's lobby.
